upon a carriage which oscillates in a substantially vertical plane abouta fixed axis. Normally the toolholder is stationary relative to itscarriage and the acting face of the tool is oscillated in an arc. Whenit is ded to give the tool a straight path, a device 'ought intooperation which maintains he acting tool-tace in a straight line subsitiaily tangent'to its normal curved path. 5 Jul discussion of possiblemodifications will {he postponed until the specific mechanism l shown inthe drawings has been fully described. v

provides thev recesses 18 for the-stops Q q tion by the propriatelypositioned recesses 13 on the ,means of the oppositely acting depressing1 spring k. (see Fig. 3) and elevating springs i Z Z. The depressingspring lei'sconveniently given the form of a coil spring which abuts atits upper end upon a seat 10 supplied by the bottom of an adjustingscrew 11 which threads into a part of the carriage b; and at provided bythe arm 2'. The elevating springs Z Z, one on each side of the arm 2',are attached at one 1 end to the carriage and at the other end to saidarm. A tool-holder m is supported on the outer end of the-supporting armand is arranged to partake of such yielding as the arm 71 may have underthe influence of the springs 7c and Z Z.

A cylindrical sleeve n rigid with the arm constitutes the immediatesupport for the' tool-holder which is so mounted as to be rotatableonsaid sleeve. The outer end of the sleeve n is screw-threaded toaccommodate a nut 0 which serves to prevent displacement of thetool-holder lengthwise of The tool-holder being rotatable about thesleeve 11, it is desirable that some means be supplied for holding it inone or more predetermined positions. To this end a non-rotatable pin 2is provided, extending through the sleeve 11., and having on its innerend rigid stops q g which project into ap tool-holder tosecure thelatter against rotation. The stops qq are held in engagement with therecesses 13 by means of a spring 1', encircling the outer end of the pin19, which abuts at one end against the sleeve n and at the other endagainst a head 8 on the pin 12. When it is desired to rotate thetool-holder, the head .9 is pressed inwardly to move the pin 1- andwithdraw .the stops 9 g from the recesses 13, whereupon the holder isreleased and may be rotated at will.

For purposes presently to be elucidated the tool-holder comprises a bodymember and an auxiliary member B. The body member A supplies the hub ofthe toolholder which rides on the sleeve n, and also (see Fig. 4). Astud t projects fromthe body member to aiford means for attachingan edgesetting tool T as shown in Fi 3. The auxiliary member B is bifurcated,iaving two parallel fingers C C arranged to fit easily in appropriatelyformed ways D D in the body member. (See Fig. 5). Thus the auxiliarymember B is permitted to move relatively to the body member A. This inone direction by th'e C C contacting with the heads of screws to u,carried by the fingers C C, which" overlie steps 14 on the body memberas shown in Fig. 6.. Sprin s E E are linterposed between seats,stationary on the carria 'e A walls of the plate 00 provi edrespectively on the body member and the auxiliary member to cushion themovement of the latter relative to the former (see Figs. 5 and 6).springs are positioned in sockets 'u v ontthe body member. The effect ofsaid. springs For convenience these E E is to ofier a yieldingresistance to movement of the auxiliary member towardthe sleeven. A studw for attaching a second edge setting tool WV is carried by theauxiliary member diametrically opposite to the corresponding stud t onthe body member. By rotating the holder through one hundred eightydegrees from the position shown in Fig. .3, the tool W on the stud wwill be removed fiom its lowermost station, which is l the'operativeposition for either tool, and

will be replaced by the tool T. It is customary to use different toolsfor setting shank edges and forepart edges and for the purposes of thisparticular machine it is preferred to attach the forepart tool W to thestud w and the shank tool T to the stud t, and either may be broughtreadily into operative position as already described. \Vhen the shanktool T is in' use the tool-holder is g 1), (except as it he movedimmaterially under the inand the ath to edge; it is T 0 Hill liue iice'of the springs'lc and'l Z), tool-face moves 1n a convex curved suit theconcave outline of the sham but when the forepart tool W is in usedesired to give the tool a straight path.

this end a straight-path device is employed comprising a concavecam-face F an .a cooperating lug G. The cam-face F isconvenientlysupplied u on an edge of a plate arigidly secured to t e outer end ofthe nonrotatable stud a. The end of said stud a.

may be split and provided with a screw- 3 threaded aperture to receiveascrew y having a frusto-conical head which, when screwed inwardly onthe stud a, serves to spread its split end to grip the. encircling tSseeFig. 3). The lug (l, as shown in the Marin s, projects upwardly from thesurface oft A and is rigid therewith. The lug is so positioned that itsupper face contacts with the cam F when the stud w is lowermost and theforepart toolis in operative osition (see Fig. 3). The lower face of t elate a: is inclined on both sides of the cam- 1 to supebody member plycams 2 which'serve an end presently to v lows: In setting a shank edgethe shank tool T is lowermost. ,The lugGr. is out of engagement with thecam F which. therefore has no oflice and the tool oscillates in' acurved path. Thefsprings 7;: and -Z Z perm tthe tool to" yield inresponse to; irregularities on the we to absorb some shank edge and alsose of the vibration oceasione'dby therapid movement of the tool. When itis desired to set the fore'part edge'the tool-holder is is thus given 2:

This forces the tool holder outwardly tor-:avd the out j j against thoitei When the tug (l reaches t extreme of its movement lt Wiil havehccndepressed to the position indicatcd by the line it; (Fig. 7), and at thesame time tho tool I will have been depressed to the position shown byline 17'. The line i? is substnntiall tangent to the curved path 18which would he taken by the tool, in the coin-so of normal oscillationwith the. arms j j, if the straightdinc device were eliminated. As thetool-holder leaves its extreme position and begins its return movementhe tool returns gradually to its initial position relativc to theguide-arms j in moving to its other cxtrcmc, the lug G is againdepressed, the. acting face of the tool W being maintuinod all the whilein the path indicated by the lill: 17, except as it may he removedtherols-om inunuterially by tho springs E E yielding as licreinufici' dscribed. The tool rcciprocating movcincnt, and in llaii term reciirocating movement, as used in this specification and tho appendedclaims, is meant a backward and i'orward movem nt in is right line. Byagain rotating tho tool-holdw about the sleeve n the shank tool may hebrought into notion and the straight-path oevicc disorganized so as toho of no el'tcct. When the parts are in proper position for setting aforcpart edge it is cvidcnt; that. thc tool-holder itself is prcventedfrom yieldingupivardly by the rigid plnte .1 eu srag ing the lug (i; butthe springs E- E, interposod between the body member A and the auxiliarymember B of the tool-holder, serve as a yielding cushion for theforepart tool and in that regard per form the same oliice for thetorepart tool which is performed for the shank the springs 7.: and Z Z.

The specific mechanism shown in the drawings has been presented forillustrative purposes only. and shows but a singl'e cn'n bodimcnt of theinvention. Obviously a tool of any sort could be attached to the studu:, and the cam F might be so slinpcd as to give to said tool anydesired path. Several cams of ditlercnt sorts mightbe provided as shown,for example, on a platc X in Fig. 8. Said plate X might be. substitutedfor the plate :1! shown on the machine in the drawings. and the cams"20, 21 and (can ried by said platc X) could be introduced respectively,into engagement with the lug G, or other device, by looscning the screw1 moving the plate Xso as to bring the desired cam into propcr stationand then tightening' the screw 1 ()t' (-oursv othcr m nus for securingthe plate X in position might be employed. such arrangement as thenon-rotatable pin p with its stops 7 could be arranged to cnproperlypositioned reccsses on the plate X. Also the cam might be carriedotherwise than on a plate of this sort. Al though it is thought moreconvcnient to cmploy two tools of different varieties it is cvi dontthat one tool could be omitted, and With the arrangement of the plate Xjust described the remaining tool could be given any desired paths ofmovement. All such modifications as are here suggested, and many otherswhich will be readily apparent to those skilled in the art, are to beconsid ered as included within the proper scope of this invention asitis defined in the subjoined claims.
